Threaded Flanges

Supplier & Stockist of Threaded Flanges

Threaded flanges are a type of flange designed with a threaded bore that allows them to be easily assembled to pipes without the need for welding, making them ideal for applications where welding is impractical or hazardous. These flanges are extensively used in piping systems carrying liquids, gases, or chemicals, especially in high-pressure environments. Their primary advantage lies in their ease of installation and removal, as the threaded connection allows for quick assembly and disassembly without specialized equipment. Threaded flanges are widely adopted in industries such as petrochemical, chemical processing, water treatment, oil and gas, and power generation, where maintenance access and flexibility are critical.

At Neonox Overseas, we supply high-quality threaded flanges manufactured according to international standards, including ANSI/ASME, ASTM, DIN, and EN. Our threaded flanges are available in various materials to suit different operating environments, ranging from standard carbon steel to corrosion-resistant stainless steel grades, including 304, 304L, 316, and duplex stainless steel. In addition, alloy materials such as nickel-based alloys are also offered for applications requiring extreme temperature or chemical resistance. Each material is selected and processed to provide optimal mechanical strength, dimensional accuracy, and resistance to corrosion and wear.

Threaded flanges come in several types, including slip-on, socket weld, and blind variations, each designed for specific applications. Slip-on threaded flanges are versatile and easy to align, while socket weld threaded flanges provide a secure connection for small-diameter high-pressure systems. Blind threaded flanges are used to terminate piping systems or isolate sections for maintenance. We also provide threaded flanges in different pressure classes, ranging from ANSI Class 150 to Class 2500, ensuring compatibility with a wide spectrum of system requirements.

Our flanges are subjected to rigorous quality checks, including dimensional inspection, material testing, and pressure testing, to ensure compliance with industry standards and customer specifications. Threaded flanges from Neonox Overseas are engineered for durability, leak-proof performance, and reliability, ensuring long-term service even in demanding industrial conditions. By offering a combination of material variety, dimensional precision, and manufacturing excellence, our threaded flanges provide a cost-effective, safe, and efficient solution for industrial piping needs.
